DETAILED DESCRIPTION OF THE INVENTION

In order that those skilled in the art can further understand the present invention, a description will be described in the following in details. However, these descriptions and the appended drawings are only used to cause those skilled in the art to understand the objects, features, and characteristics of the present invention, but not to be used to confine the scope and spirit of the present invention defined in the appended claims.

With reference to FIGS. 3 to 5, the physical protection device of the present invention is illustrated. The physical protection device has the following elements.

A receiving chamber 1 has an inner tube 10. At least one bullet 3 is placed in the inner tube 10. A front end of the inner tube 10 is tapered with an opening formed at a foremost thereof. A top of the receiving chamber 1 is installed with an emitting key 11. Each of two lateral side of the receiving chamber 1 is formed with a slot 12 and a buckle 13.

A base 2 is included. Each of two sides of the front end of the base 2 has a tenon 22 corresponding to the slot 12 and an ear 23 corresponding to the buckle 13. An interior of the base 2 is installed with a push rod 24, an impact unit 25 and a stud 26. A bottom of the push rod 24 has a quick restoring spring 241. A rotatable handle 27 is pivotally installed to a bottom of the base 2. One end of the rotatable handle 27 resists against a front end of the impact unit 25 and another end of the rotatable handle 27 is a free end. To push the rotatable handle 27 to pivotally rotate, the impact unit 25 is pushed to move backwards to compress the spring 241 to store energy. Meanwhile, by the lock of the stud (referring to FIG. 6), the push rod 24 move backwards due to the action of the emitting key 11 to move axially. A rear end of the push rod 24 pushes the stud 26 to unlock. The impact unit 25 is ejected by the resilient force of the spring 251 so as to impact a rear end of the spring 251. A rear end of the spring 251 is formed with an expansion chamber 31 which is filled with powder. A front end of the bullet 3 is filled with liquid 33. The liquid 33 is stimulus liquid or dyes. A valve 34 is installed between the liquid 33 and the expansion chamber 31. Furthermore, to have a safety effect, two sides of the base 2 are installed with safety buttons 28 corresponding to the rear end of the push rod 24. When the safety button 28 is pushed, the push rod 24 is released (referring to FIG. 7). Namely, if it is desired to push the emitting key 11 to trigger the bullet 3, the safety button 28 must be pushed so as to further push the push rod 24 to unlock the stud 26 so that the impact unit 25 impacts the expansion chamber 31 at the rear end of the bullet 3 to trigger the filled powder to act. Thereby the valve 34 will extrude the liquid 33. A strong internal pressure will destroy a front end of the bullet 3. Meanwhile the liquid 33 sprays out from the opening of the inner tube 10.

Referring to FIGS. 8, another embodiment of the present invention is illustrated. The inner tube 10 a of the receiving chamber la is a straight tube. A rear end of the bullet 3 a is an expansion chamber 31 a. The liquid 3 a is filled into an easy breakable short cylindrical container 34 a made of such as plastics or rubber. The containers 3 a is installed at a front end of the bullet 3 a. The user pushes the emitting key 11 a so that the push rod 23 pushes the stud 26 to unlock. Thereby the impact unit 25 will impact the expansion chamber 31 a at the rear end of the bullet 3 a to trigger the powder to act. As a result, the container 34 a is ejected out from the opening of the inner tube 10. As the container 34 a impacts a devil person, he (or she) will feel ache and the container 34 a will break. The liquid 33 a will spray upon the body of the person to achieve the effect of protecting the user. This embodiment has the effect of increasing the traveling length of the bullet 3 a. Thereby if the liquid 3 a within the container 34 is dye. It has the effect of make an indication to the devil person.
